Scientists make mistakes, but when you want advice on genetics, the best person to ask is a geneticist. People who know what they are talking about are the best people to ask on any given subject & it just so happens that people who know what they are talking about on any given field just happen to be labelled as scientists.
Big FUCKING Deal!
They're still human beings, just like me or you. Scientists are know more or less human than us, they just happen to know a lot about whatever it is they studied at university, which is a good thing surely? Wouldn't you rather get advice from someone who has put in the time to study? Someone who is demonstrably intelligent?
Nope, you'd rather get advice from an archaic book which is at best a piece of shit.
